Public bug reported: I think the "Books" app included in GNOME is so incomplete that it would be better to set NoDisplay=True for it.
What happens when you launch GNOME Books === Books opens, showing you the .cbr, .cbz, .djvu, .mobi, .epub files it finds in your tracker-searched folders. The only file type it lets you actually view though is .cbr and .cbz (which are usually used for comic books). For everything else, it displays an uphelpful error message: https://git.gnome.org/browse/gnome- documents/commit/?id=9c5cf3e98c15c17736bacda1aa2eea9458cbf4ce Since the evince "Document Viewer" can also display .cbr and .cbz files just fine, GNOME Books is redundant. Worse, "Books" implies that it will let you read commonly used ebook formats such as .epub or .mobi but it cannot. GNOME Books development is slow. The initial Books feature is a year and a half old and the "coming soon" message is a year old. https://git.gnome.org/browse/gnome-documents/log/?qt=grep&q=books Once Books gets epub support, we should probably show the Books app again.
